Polistes (Aphanilopterus) brevifissus Richards Paramere (Fig. 5A): (1) about three times longer than wide at the middle; (2) lateral groove deep, more pronounced on the upper part; (3) parameral spine long (about 1/6 the total length of paramere), pointed apically with long and dense bristles, mainly on spine base; (4) paramere lobe developed and widely rounded; (5) inferior portion of paramere narrow, about half the width at the middle portion. Aedeagus (Fig. 5B, C): slender; (1) apical portion with fine and serrated denticulation, extended the apex of the apical portion to the median expansion, lateral margin straight; (2) penis valve weakly dilated and with a slight central entrance (about 1/3 of the total length of apical portion); (3) median expansion developed, rounded apex; (4) lateral apodeme directed forward, with a weak central projection and shorter than the ventral process, (5) ventral process rounded; (6) inferior portion of aedeagus curved, in lateral view. Digitus (Fig. 5D): slender; (1) apical process developed, about twice longer than the digitus base, same width from the base to the apex, (2) apex rounded; (3) anteroventral lobe short and rounded apically; (4) punctation strong and forming a central band around the base of the digitus; (5) evanescent bristles. Cuspis (Fig.5E): slender; (1) apex pointed and tapering abruptly to the end; (2) short and dense bristles on cuspis; (3) punctation restricted on the lateral lobe; (4) lower part developed with short bristles. Remarks. Richards (1978: 481–482) did not describe the male genitalia of this species. He only commented that the male is very similar to the female.
